I rushed Hello Dolly on Friday night, in case people wanted info on my experience:
I got to the line at 8:30AM, and was able to secure a ticket. They had 15 SRO tickets available for the evening, but they also had balcony for $59 that people behind me were able to get once the SRO sold out. The couple of people in front of me all came around 7:45 and the first person in line got to the Schubert around 6:15AM I believe. 3 people in front of me were looking for single tickets, so I knew I was in. Had they not, I wouldn't have made it (though someone thought they would have 20 SRO, that wasn't the case for us). As I'm sure already people have mentioned, SRO is great.
Not to get on a soapbox because I"m sure people here agree, but it's really annoying when people take pictures during the show. You know you're not supposed to, and you are also forcing the usher to shine a flashlight which distracts from the show. That was frustrating, and it sometimes blocked my view.
Finally, this was my first time seeing Hello Dolly on Broadway/any professional production, and it was hilarious and well done. Bette Midler went HAM, enjoyed the audience, and the audience loved her. DHP was excellent, as I knew he would be. Gavin's voice and acting was on point, and I also really enjoyed Kate Baldwin (my first time seeing her). Great show, glad I was able to see it, and I'm sure Donna Murphy is amazing too, but the way Bette plays with the audience - glad I was able to witness that.
